Summary
This review explores Alzheimer's disease (AD) progression by examining patient dependence. It proposes a framework to understand how cognitive, functional, and behavioral changes increase the need for care and support.
Area of Science:
- Gerontology
- Neurology
- Public Health
Background:
- Alzheimer's disease (AD) is clinically characterized by impairments in cognition, function, and behavior.
- These impairments progressively lead to increased patient dependence and loss of autonomy.
- Current literature often treats these domains separately, with limited focus on patient dependence as a progression metric.
Purpose of the Study:
- To review measures of Alzheimer's disease (AD) progression in relation to patient dependence.
- To offer a unifying conceptual framework for understanding dependence in AD.
- To present patient dependence as a method for a holistic description of AD progression.
Main Methods:
- Literature review of studies measuring AD progression.
- Analysis of the relationship between AD clinical domains (cognition, function, behavior) and patient dependence.
- Conceptual synthesis to develop a framework for dependence in AD.
Main Results:
- Patient dependence increases across AD stages, from needing reminders to requiring significant assistance with basic functions.
- Changes in cognition, function, and behavior collectively contribute to escalating dependence.
- A conceptual framework is proposed to integrate these domains into a holistic view of AD progression.
Conclusions:
- Patient dependence offers a transparent and holistic descriptor of Alzheimer's disease progression.
- This framework can translate clinical changes into a clearer understanding of care needs.
- Further research can utilize this framework to better assess and manage AD progression.

Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...

Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
Dementia
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.
